• Connect a device gathering various Video sources
• Provide flexibility to allow the DCU to be used in slave mode (external synchronization)
The PDI features the following:
• Supported color modes:
— 8-bit mono
— 8-bit color multiplexed
— RGB565
— 16-bit/18-bit RAW color
• Supported synchronization modes:
— embedded ITU-R BT.656-4 (RGB565 mode 2)
— HSYNC, VSYNC
— Data Enable
• Direct interface with DCU3 background plane FIFO
• Synchronization generation for the DCU3
1.5.14 Display Control Unit Lite (DCULite)
The DCULite is a display controller designed to enable the PXD20 to drive a second TFT LCD display up
to XGA resolution using direct blit graphics and video. The DCULite includes all features of the DCU3,
including the PDI with the following exceptions:
• Reduced from 4-plane to 2-plane blending
• Reduced from 16 layers to 4 layers
• Reduced CLUT size
1.5.15 Timing controller (TCON) and RSDS interface
The TCON enables direct drive of the row and column drivers of display panels enabling emulation of
TCON ICs used in display panels.
• Programmable Timing Generation unit featuring 12 waveform generators allowing high degree of
flexibility in panel waveform generation
• Reduced Swing Differential Signaling (RSDS) interface for RGB data and pixel clock
• Conforms to “RSDS ‘Intra Panel’ Interface Specification” Rev. 1.0 (National Semiconductor)
1.5.16 RLE decoder
The RLE decoder is a crossbar slave sharing a slave port with the QuadSPI module. The platform eDMA
is used to stream compressed image data into and extract decompressed data out of the RLE Decoder.
• Lossless decompression
• Pixel formats supported: 8bpp, 16bpp, 24bpp and 32bpp
• AHB mapped read and write registers in RLE_DEC to achieve higher throughput
